贵州紫云扁平剖面紫松阶上部—罗甸阶非■有孔虫动物群由25属82种(含相似种、亚种而不含未定种)构成,其中7属(Cribrogenerina、Nodosaria、Glomospira、Tetrataxis、Palaeotextularia、Climacammina及Globival-vulina)的物种分异度最高,合计占总种数的71%;该动物群自紫松期开始发育,在隆林期类群构成发生显著变化并繁盛至罗甸早期,在罗甸中晚期明显衰落。研究剖面由下至上可划分为Cribrogenerina celebrata-C.hemispaera间隔带、Glomospira-Nodosaria富集带(又可进而分为Geinitzina postcarbonica-Globivalvulina cyprica间隔亚带、Climacamminaelegantula延限亚带)、Lasiodiscus-Eotuberitina间隔带。
The upper part of the Zisong terrace in the Ziyun flat section of Guizhou is composed of 82 genera and 25 species (including similar species, subspecies but not undetermined species) in non-foraminiferal order of Luodendian, of which 7 genera (Cribrogenerina, Nodosaria, Glomospira, Tetrataxis, Palaeotextularia, Climacammina and Globival-vulina) had the highest species diversity, which accounted for 71% of the total species. The animal population developed from the beginning of the stage of Vigor and the composition of the taxa changed significantly in Longlin period, Early, in Luoding significantly decline in the late. The study profile can be divided into Cribrogenerina celebrata-C.hemispaera spacer, Glomospira-Nodosaria spacer (which can be further divided into Geinitzina postcarbonica-Globivalvulina cyprica spacer and Climacamminaelegantula extension limit), Lasiodiscus-Eotuberitina spacer .
